A floating litter collection system for collecting floating debris from the surface of water flowing in a water stream, comprising a wire mesh container having an open front end, a first buoyant device secured to a first side of the container, a second buoyant device secured to the second side of the container, and a pair of mooring lines for anchoring the container to the water banks of the water stream. The system may include a pair of floating booms secured to the mooring lines to direct debris floating on the surface of the water into the container. The system may include a fin attached to the bottom of the container to orient the front end of the container in an upstream direction. The system may include a floating anchor to orient the front end of the container in an upstream direction.

The invention provides a composite and modular intermediate deck, designed to divide a micro home into an upper living volume and a lower living volume below the intermediate deck. The intermediate deck is characterized by having a U-shaped slot comprising from 10% to 60% of the total surface of the platform, which allows maximizing usage of vertical space by making the U-shaped slot, which serves as a corridor in the upper living volume, coincide with non-crossable spaces in the lower living volume. The height of crossable areas of the upper living volume is given by the distance from the floor to the flat surface of the intermediate deck. A micro home unit characterized by featuring the abovementioned deck is also provided.

A recreational vehicle (RV) includes a ramp door configurable as a ramp or as a patio deck. A stair is attachable to a side of the door. A railing extends about the perimeter of the door when in the deck configuration. First and second support cables may be connected between the door and the RV to support the door when in the deck configuration.

A ramp assembly in accordance with one embodiment of the present disclosure includes a decking system and a handrail system, and an interface between the decking system and the handrail system and a support system pivotably coupled to the interface. Other embodiments include a swivel bracket and a method of assembling a ramp assembly.

A construction assembly and methods for making and using the same. The construction assembly includes a plurality of primary structure members each having an S shape including first and second portions respectively defining first and second level recesses. The primary structure members can be in a standing position with the first and second level recesses being respectively proximal to and distal from ground. The first portions can collectively surround and define first level space. The second portions can collectively surround and define second level space greater than the first level space. Advantageously, the construction assembly can provide an efficient space-generating solution. Because of the smaller floor area of the first level space, environmental hazards such as wind, flood or tsunami can exert smaller impact on part of the construction assembly proximal to the ground. Advantageously, the primary structure member can be lightweight, strong and easy to assemble.

In one implementation, a stair system disclosed herein allows for efficient manufacturing and installation of stairs. The stair system includes a stair comprising a plurality of steps, a lower landing rotatably attached to the bottom of the stair, and an upper landing rotatably attached to the top of the stair, wherein each of the upper landing and the lower landing are configured to be attached to vertical posts.

A stairway (1) comprising a plurality of steps (2) each defining a top surface or tread (3) is converted into a lift platform by employing a mechanism concealed beneath an envelope defined by the treads of all of the steps to guide each step of the plurality vertically from a stairway configuration in which the steps form a stairway enabling access from a lower (7) level to an upper level (8) to a flat configuration in which the top edge of each step is substantially in a horizontal plane level with one of the lower and upper levels from which a wheelchair user may wish to travel to the other of the lower and upper levels. As a result, a wheelchair user may move horizontally from the said one of the lower and upper levels on to a platform defined by the top edges of the plurality of steps in the flat configuration. The stairway and flat configurations occupy the same footprint.
